e My invention relates to lrotary graters. The object Voi' the Vinvention isto provide `a e rotary grater .especially adapted to grate the curved broken pieces ',ofcoconut end-'Wise of thenpieces instead of 'fiat-'Wise as heretofore. The'invention 'consists in providinga ro-'v tary grater Ywith 'a lhopper curved outwardly and upwardly from one' -side of the `grater and shaped internallyto receiveand guide broken pieces of .coconut'endwise' and guide them to the 'rotaryxgraterz to provide a lever pivoted concentrically to 'the curved hopper and having a presser bar between its ends tting withint-he curved hopper to force the coconut vtowards' the rotary grater: `also to provide the lever with two parallel arms to' which the ends Yof `the presser bar 'are'secured and toprovide the sides of the hopper with curved slots in which the ends of the presser bar work: also to providethe lever beyond the presser bar with inturned ends and form it in a single piece with its handle portion and presser bar.

These objects I accomplish by the construction sliown in the accompanying drawing, in which Figure 1 is a sectional side elevation.

Figure 2 is a section on line 2, 2, Figure 1.

Figure 3 is a plan, and

Figure 4 is an end elevation showing the machine in position for use.

The frame of the machine comprises parallel circular end pieces 1 and 2 from which project the curved hopper 20. The end piece 1 is in the form of a disk recessed on its inner face to receive one end of the cylindrical casing 5, and provided with a central shaft bearing 6, while the other end piece 2 is in the form of a ring which receives the open end of the cylindrical casing 5. This ring 2 is provided with an upstanding apertured lug 7, having a recess 8 in its outer face which receives the inturned end 9 of a` bearing arm 10; a bolt 11 and thumb screw 12 serving to hold the arm 10 in place. The free end of the arm 10 is provided with a bearing aperture 13 in horizontal alignment With the shaft bearing 6. The cylindrical grater 15 is closed at its end next to the end piece 1 and open at the opposite end so as to discharge therefrom the grated material entering the grater through its curved outwardly projecting teeth 16. The closed end of the grating cylinder 15 carries the shaft 17 mounted at one end in the shaft bearing 6 and at its opposite end mounted in the or nAsroN,-.i.e.nYLAND.

The hopper is therefore of eX- tended width, comparatively narrow and curved` both longitudinally and transversely. The ends of the hopper 20 are provided with vcurved slots 21-21 concentric withv the axis 22 of a pair of lever arms 23 having an integral presser bar 24 connecting them in a rigid manner and guided at its narrowed ends 25 in the slots 21. The outer ends of the lever arms 23 are offset inwardly as at 24 and connected by an integral handle member 25". In other words the lever arms 23, presser bar 24 and handle 25 are" cast in a single piece. rIhe inward offsets allow the pan which receives the discharge from the grater to be placed` further under the grater than would be the case'were the arms un rovided withv these offsets 24. he machine may be readily taken apar for cleaning b simply removing the handle and thenbackmg olf the thumb nut to allow the bearingy arm 10 to be moved from the shaft whereupon the grating cylinder and shaft may be removed.

I am aware that cylindrical graters having hoppers and lever carried presser bars are old, but I do believe that I am the first to so shape the hopper as to hold the curved from theend piece 'l is the piece of coconut in proper position to present its end to the grater, which 1s a great improvement over presenting the piece flat- Wise, asthis latter method causes the meat While designed specifically for grating coconut the machine will be found useful in grating other substances, but with my invention the housewife may readily prepare freshly ground coconut and not be restricted to using the dried packaged product.

Having described the invention what I claim is:

l. A grater provided with a feed hopper having its feed passage curved and dimensioned to receive and hold flatwise, broken pieces of coconut and present the same endwise tothe grater proper; the sides of the hopperbeing provided with curved slots, a lever pivoted concentrically to the hopper and having parallel side bars exterior tothe side of the hopper, an intermediate pressure bar connecting the side'bars, working in the hoppervand having its ends guided in the curved slots and a handle bar connecting the ends of the side bars.

2. A grater provided with afeed hopper having its feed passage curved and dimensioned toreceive and hold latwise, broken pieces of coconut and present the same endwise to the graterproper; the sides lof vthe hopper ,being provided with curved slots, a lever pivoted concentrically to the hopper and having parallel side barsy exterior to the sides of the hopper, a pressure bar connecting the side bars between their ends and guided at its ends in said curved slots; the free ends of the sideY bars being odset inwardly and a handle bar rigidly connecting said offset ends.

3. A grater comprising side members, one of which lis closed and the other an open ring, a cylindrical casing mounted in the said members and having an inlet opening at one side, a grater cylinder having a central shaft mounted at one end in said closed member and there provided with an operating handle, a movable shaft support fory the opposite endsof the shaft and supportedL from the open ring, a feed hopper projecting from the said side members integrally'there-V LEVVIN H.
